Taking the example of aqueous slurries of calcium hydroxide absorpting carbon dioxide,we study the reaction of gas-liquid-solid three phases with the solid participating chemical reaction and give a model of it In order to verify the model we proposed,we made the experiment of absorption of carbon dioxide into aqueous slurries of carbon dioxide into aqueous slurries of calcium hydroxide Through experiment,we found that the observed results of absorpotion of carbon dioxide into aqueous slurries of calcium hydroxide were accordant with the results predicted by proposed model
